Dreaming back to 90, starting to develop B2 bombers!

Railgun!Finally, after about half a month, Yu Bei finally walked out of his office. At this time, his condition was very poor, and his fatigue was visible to the naked eye! !

When a group of academicians saw Yu Bei like this, they were very worried and couldn’t help but ask,

“Yu Gong, what’s wrong with you? Are you feeling unwell?”

“Yes, Yu Gong, do you want to take a break and let the academicians from the medical school come and take a look at you!!”

“Yu Gong, you have to take care of yourself. If you have any shortcomings, what’s the point of us being on this Mars base?!”

Seeing the sincere concern of the group of musicians in front of him, Yu Bei was deeply moved. Then he nodded and said, “Everyone, I have nothing to do. I just need to rest for a few days. You all should be busy with your own affairs first.” Go ahead, we will start a new project in two days!!”

In the past, everyone would be excited when they heard about a new project. But today, seeing Yu Bei so exhausted and overworked, the original good news made all the academicians unable to get excited for a while. He nodded with worry and returned to his post! !

And Yu Bei also returned to the lounge, made himself a cup of tea, and sorted out his thoughts! !

At present, he has finally gathered enough energy points. The next thing to think about is what kind of technological weapon he wants to make! !

For a moment, many movies he had watched in his previous life, games he had played, and random news flashed through Yu Bei’s mind, and he was thinking about what kind of technological weapon he was going to make! !

But even so, it was not determined for a while. After all, this technological weapon is simple to come up with. In fact, based on the development of mankind for so many years, with full use of imagination, it is not possible to think of high-end technological weapons. Not as many as expected! !

“Which one should we choose? When the time comes for foreign civilizations to come, we must have sufficient defense!!”

“Otherwise, this Mars base will be in name only and cannot even provide the first layer of protection!!”

Yu Bei stared at the ceiling with his eyes and murmured in a low voice! !

Suddenly, as if he thought of something, Yu Bei’s eyes suddenly lit up, and he became excited! !

He suddenly thought of the movie he saw before! !

The defense facility used by the alien civilization in that movie was a cannon! !

The power of that kind of running is very powerful, and some can even kill a spaceship with one shot. I believe that even if the desire civilization comes, their transportation carrier will not be much better than the spaceship! !

“That’s right, rail guns, this thing 840 is called a rail gun!!”

Yu Bei’s eyes lit up as he remembered the name of this technological weapon. He suddenly became excited, and then he immediately said in his heart,

“The system wants to conduct a directional lottery!!”

“Directional Lottery Railgun!!”

“Ding!! Does the host spend 4,000 energy points on a directional lottery?!”

The mechanical sound that he had not heard for a long time rang in Yu Bei’s heart! !

“Sure!!”

A light flashed in Yu Bei’s eyes, and he said extremely firmly.

“Ding! Congratulations to the host for spending 4000 energy points!! Congratulations to the host for obtaining the rail gun design drawing!!”.
